Answer:

Definition of centenarian

A centenarian is a person who has reached the age of 100 years. Because life expectancies worldwide are below 100 years, the term is invariably associated with longevity. In 2012, the United Nations estimated that there were 316,600 living centenarians worldwide

As life expectancy is increasing across the world, and the world population continues to increase rapidly, the number of centenarians is expected to increase quickly in the future.

Explanation:

According to the UK ONS, one-third of babies born in 2013 in the UK are expected to live to 100.The United Nations predicts that there are 573,000 centenarians currently, almost quadrupling from the suggested 151,000 in the year 2000.other sources suggest that the number could be closer to 1 million.The incidence of centenarians in Japan was one per 3,522 people in 2008.Research in Italy suggests that healthy centenarians have high levels of both vitamin A and vitamin E and that this seems to be important in causing their extreme longevity.[84] Other research contradicts this, however, and has found that this theory does not apply to centenarians from Sardinia, for whom other factors probably play a more important role.[85] A preliminary study carried out in Poland showed that, in comparison with young healthy female adults, centenarians living in Upper Silesia had significantly higher red blood cell glutathione reductase and catalase activities, although serum levels of vitamin E were not significantly higher.[86] Researchers in Denmark have also found that centenarians exhibit a high activity of glutathione reductase in red blood cells. In this study, the centenarians having the best cognitive and physical functional capacity tended to have the highest activity of this enzyme.[87]
